Example of silicone mastitis after silicone injection in the breast. A 47-year-old woman who received silicone injection had a suspicious lesion in the left breast on magnetic resonance imaging (MRI) screening. (A) Axial contrast enhanced T1-weighted image showing oval, smooth, heterogeneous enhancing mass in the left breast, which was categorized into American College of Radiology Breast Imaging Reporting and Data System category 4a. (B) Dynamic time-intensity curves of the lesion showing an initial fast uptake followed by a fast washout in the delayed phase (type III). (C) Sagittal, T1-weighted subtracted dynamic image acquired immediately before biopsy showing heterogeneously enhancing mass in the 12:00 hours position. (D) Sagittal T1-weighted subtracted dynamic image acquired after placement of the obturator showing low signal within the lesion (arrow), indicating the location of the obturator tip. (E) Sagittal T1-weighted subtracted dynamic image immediately after completion of tissue acquisition showing hematoma formation at the biopsy site. Histologic analysis demonstrated silicone mastitis.
